Cap # 910-15707 will work fine with this filler neck. It has a two part lock on the neck and you have to tighten to the second lock.

This manifold filler neck is specified for the GM applications of V8’s and 90* V6. It may be adaptable to other applications but you will need to verify intake compatibility from the following dimensions. * 3 ¼” center to center mounting pattern * 2 5/16” tall * 1 ½ hose neck * 2—1/4” NPT and 1—1/2” NPT ports for heater hose or cooler line options * Filler neck has hose barb for overflow line * 9/16 bolts and gaskets included * Cap is NOT included Thermostat size is standard to the GM applications and could possibly cause problems with use in different applications. You may want to check with Moroso for availability for your particular application.
